Madonna, Taylor, Lana: Which Kristen Wiig Im-pop-sonation Is Best?

Long before Kristen Wiig went toe-to-toe with the undead as Ghostbusters' resident brainiac Erin Gilbert, she was killing Saturday Night Liveviewers with pop star-impressions that shook the industry more forcefully than the birth of Napster.

In honor of Wiig's 43rd birthday (thank you, August 22, 1973), we're looking back at some of the comedian's most memorable takes on music's most eccentric stars. Between Bjork's childish affectation and Lana Del Rey's seeming aloofness, we'd say she pretty much nailed 'em all — but take our poll and tell us which shines brightest in the comments.
